They fusible links 1l are made of any Well knnwn metal 0i- :illoy which will melt at a uonipni'utively low temperature, as for in stanco. 165 F.. :so that whenevei' any portion ci the door through which the chain passes is heated t0 Such :i temperature, the same will be severed by a melting of one of the t'usible links and the bolt will automatically drop into operative position.

A single anxiliary bolt may be suspended in a way located in the median line of the door, thereby passing in front ot or adjacent to the ordinary locking` device 29 and 29 and the timing' device Qt) by which the ordinary lockingl system is actuated and controlled. so that' any etl'lort which may be made to cut through the door by an ox v' acetylene torch or the like, will necessarily heat the adjacent portions ot the body of the door to such a degree that' one or more ot the t'usible links will be melted and the anxiliary bolt released to lock and secure the door. even though the ordinary locking' system may be opened.

In the moditied arrangement shown in Figs. (i and T, the auxiliaiy bolt S is located in guides 15 mounted on the back ot the door i6 and the chain comprising' the ordinary links l0 and the fusible links Yll may be suspended in a retracted or inoperated position from a suitable support 1;" secured to the back of the door, and extend along and near the body thereot'.

The proximity to the hack ol' the door ot' the fusible link chain by which the bolt is suspended, will cause the links to he atlected by any abnormal or extraordinary heat to which the door or any adjacent portion ot' it" may be subjected, with the result that the fusible links will be melted and the auxiliary bolt dropped into locking position, the saine as described for the preferred arrangement ot the same.

Ordinarily a single auxiliary bolt suspended in the median line ot the door will be sutl'lcient for all practical purposes, but a plurality ot' auxiliary bolts may be located at spaced intervals apart so as to cover substantially the entire width ot' the door, and protect any vulnerable portions thereof which may be exposed to malicious attack.

l claim l. n anf-:iliary lock tor sate doors or they like including' a vertical guide-way therein, a bolt-weight in the guide-way. and a chain connected above to the door and extending downward along' the body thereof to be directly heated thereby and having a plurality ot' tusible links therein normally suspendin;Y the bolt in retracted position.

2. n auxiliary lock tor sate doors or the like including;Y a vertical guide-way within the body thereot' to he directly heated thereby. a bolt-weight in the guide-way and a chain in the `guide-way connected above the door and havinj.;- a plurality ot 'fusible links therein normally ,--11speIidi11;` the holt in reA tracted position.
